Your MPH is terrible. The only reason you got a 13.5 was your terrific launch on street tires. If you would have had a 2.2 60' (which is common for guys new to the track) you would have been somewhere around 14.0 @ 100.
What was the track elevation? How hot and humid was it when you ran? On a 90 degree day with a 700 foot elevated track I pulled a 13.5 @ 103.79 with just a lid and catback on a 2.1 60' so I'm thinking your car is a good 3-5 mph under par for trap speed. You may want to have it checked out by a mechanic or LS1 guru.
Good Luck

And you may want to consider a tune after the TC install.
13.5 is a good time in a 98' Trans Am. Also, going from a 3.42 to 3.73 will definitely need drag radials.
Good luck though.
